Creating PCB templates in CircuitStudio is possible but as of now there is not a way to do this within the software. This answer is more of a work around but we are expecting to include this in future release.
To create a template to CircuitStudio here is what you'll have to do:
1. Create your project you want to use as a template
2. Give the project, schematic, and PCB files the same name (file extension can be different)
Example:
MyTemplate.PrjPCB
MyTemplate.CSPCBDoc
MyTemplate.SCHDoc
3. Save these files here: C:\Users\Public\Documents\Altium\CS\Templates\PCB Projects
4. Add to the "PCB Project Templates.ini" file in the same folder as step 3
Using step 2 as an example we would put an entry into the INI as follows
[MyTemplate]
Category=Custom
Title= My custom project template
Description=Starter PCB w/title block, Schematic with Titleblock, Project with options set.
(you can also add an EMF image of the same name if you want a visual preview)
5. Restart / open CircuitStudio
6. Create a new project : File>New Project Here you should see a custom category in the templates list
